Lessons in Rook endgames essentials
Rook against pawn – A rook is worth much more than a pawn, but a far advanced pawn with its king beside it can still save the game. Who wins depends on the kings.
The bridge – With a rook and a pawn against a rook, the winning plan has a name in every chess book, but the idea is simple: build a bridge.
The third rank defence – Now the other side. With a rook against a rook and a pawn, a good defence draws. Keep the enemy king out, then check from behind.
